文摘Objective:To evaluate whether improved progression-free survival(PFS)from radiotherapy(RT)translates into an overall survival(OS)benefit for diffuse large B-cell lymphoma(DLBCL).Methods:A systematic literature search identified randomized controlled trials(RCTs)and retrospective studies that compared combined-modality therapy(CMT)with chemotherapy(CT)alone.Weighted regression analyses were used to estimate the correlation between OS and PFS benefits.Cohen’s kappa statistic assessed the consis-tency between DLBCL risk-models and PFS patterns.Furthermore,the benefit trend of RT was analyzed by fitting a linear regression model to the pooled hazard ratio(HR)according to the PFS patterns.Results:For both 7 RCTs and 52 retrospective studies,correlations were found between PFS HR(HRPFS)and OS HR(HROS)at trial level(r=0.639-0.876),and between PFS and OS rates at treatment-arm level,regardless of CT regimens(r=0.882-0.964).Incorporating RT into CT increased about 18%of PFS,and revealed a different OS benefit profile.Patients were stratified into four CT-generated PFS patterns(>80%,>60-80%,>40-60%,and≤40%),which was consistent with risk-stratified subgroups(kappa>0.6).Absolute gain in OS from RT ranged from≤5%at PFS>80%to about 21%at PFS≤40%,with pooled HROS from 0.70(95%CI,0.51-0.97)to 0.48(95%CI,0.36-0.63)after rituximab-based CT.The OS benefit of RT was predominant in intermediate-and high-risk patients with PFS≤80%.Conclusion:We demonstrated a varied OS benefit profile of RT to inform treatment decisions and clinical trial design.

文摘Mature T-and natural killer(NK)-cell lymphomas are heterogeneous groups of malignant lymphoid neoplasms arising from T and NK cells. The incidence of mature T-and NK-cell lymphomas is 2.1 per 100,000 people, according to a US report~1.
文摘BACKGROUND Mucosa-associated lymphoid tissue(MALT)lymphoma originates in the marginal zone of lymphoid tissue.lung is one of the most frequent non-gastrointestinal organs involved,here known as bronchus-associated lymphoid tissue(BALT)lymphoma.BALT lymphoma of unknown etiology,and most patients are asymptomatic.The treatment of BALT lymphoma is controversial.CASE SUMMARY A 55-year-old man admitted to hospital had a three-month history of progressively coughing up yellow sputum,chest stuffiness,and shortness of breath.Fiberoptic bronchoscopy revealed mucosal visible beaded bumps 4 cm from the tracheal carina at 9 o'clock and 3 o'clock,the right main bronchus,and the right upper lobe bronchus.Biopsy specimens showed MALT lymphoma.Computed tomography virtual bronchoscopy(CTVB)showed uneven main bronchial wall thickening and multiple nodular protrusion.BALT lymphoma stage IE was diagnosed after a staging examination.We treated the patient with radiotherapy(RT)alone.A total dose of 30.6 Gy/17 f/25 d was given.The patient had no obvious adverse reactions during RT.The CTVB was repeated after RT and showed that the right side of the trachea was slightly thickened.CTVB was repeated 1.5 mo after RT and again showed that the right side of the trachea was slightly thickened.Annual CTVB showed no signs of recurrence.The patient now has no symptoms.CONCLUSION BALT lymphoma is an uncommon disease and shows good prognosis.The treatment of BALT lymphoma is controversial.In recent years,less invasive diagnostic and therapeutic approaches have been emerging.RT was effective and safe in our case.The use of CTVB could provide a noninvasive,repeatable,and accurate method in diagnosis and follow-up.

文摘Four major studies(Checkmate577,Keynote-590,Checkmate649 and Attraction-4)of locally advanced esophageal cancer published in 2020 have established the importance of immunotherapy,represented by anti-programmed death protein(PD)-1 in postoperative adjuvant treatment and advanced first-line treatment of locally advanced or advanced esophageal cancer and esophagogastric junction cancer,from the aspects of proof of concept,long-term survival,overall survival rate and progression-free survival.For unresectable or inoperable nonmetastatic esophageal cancer,concurrent radiotherapy and chemotherapy is the standard treatment recommended by various guidelines.Because its curative effect is still not ideal,it is necessary to explore radical radiotherapy and chemotherapy in the future,and it is considered to be promising to combine them with immunotherapeutic drugs such as anti-PD-1.This paper mainly discusses how to combine radical concurrent radiotherapy and chemotherapy with immunotherapy for unresectable local advanced esophageal cancer.
文摘BACKGROUND Metastasis to the hyoid bone is an exceptionally rare occurrence,with documented cases limited to breast,liver,colon,skin,lung,and prostate cancers.This report highlights an unusual case involving the metastasis of lung adenocarcinoma to the hyoid bone,accompanied by a distinctive headache.Previous documentation involved surgical resection of the hyoid mass.We present a case displaying the benefits of palliative radiotherapy.CASE SUMMARY A 72-year-old non-smoking,non-alcoholic woman,initially under investigation for a year-long elevation in absolute lymphocyte count,presented with a monthlong history of intermittent throat pain.Despite negative findings in gastroenterological and otolaryngologic examinations,a contrast-enhanced chest computed tomography scan revealed a mediastinal mass and questionable soft tissue thickening in her left anterolateral neck.Subsequent imaging and biopsies confirmed the presence of lung adenocarcinoma metastasis to the hyoid bone.The patient was treated with platinum-based chemo-immunotherapy along with pembrolizumab.Ultimately,the lung cancer was unresponsive.Our patient opted for palliative radiation therapy instead of surgical resection to address her throat pain.As a result,her throat pain was alleviated,and it also incidentally resolved her chronic headaches.This is the second documented case of lung adenocarcinoma metastasizing to the hyoid bone.CONCLUSION Palliative radiotherapy may add to the quality of life in symptomatic patients with cancer metastatic to the hyoid bone.
文摘Hemostatic radiotherapy is a non-invasive treatment for bleeding gastrointestinal(GI)tumors,promoting tumor shrinkage,blood supply reduction,and fibrotic tissue formation.It is effective in cases where traditional interventions are insufficient or contraindicated and can prevent recurrent bleeding in patients with GI bleeding histories.Hypofractionation schedules are also effective for tumor control and patient compliance.
文摘BACKGROUND Primary central nervous system lymphoma(PCNSL)is a non-Hodgkin lymphoma that originates in the central nervous system(CNS)and is exclusively limited to the CNS.Although most PCNSLs are diffuse large B-cell lymphomas,primary CNS T-cell lymphomas(PCNSTLs)are rare.PCNSTLs typically demonstrate some degree of enhancement on contrast-enhanced magnetic resonance imaging(MRI).To the best of our knowledge,non-enhancing PCNSTL has not been reported previously.CASE SUMMARY A 69-year-old male presented to the neurology department with complaints of mild cognitive impairment and gradual onset of left lower leg weakness over a span of two weeks.Initial MRI showed asymmetric T2-hyperintense lesions within the brain.No enhancement was observed on the contrast-enhanced T1 image.The initial diagnosis was neuro-Behçet’s disease.Despite high-dose steroid therapy,no alterations in the lesions were identified on initial MRI.The patient’s symptoms deteriorated further.An MRI performed one month after the initial scan revealed an increased lesion extent.Subsequently,brain biopsy confirmed the diagnosis of PCNSTL.The patient underwent definitive combined chemoradiotherapy.However,the patient developed bacteremia and died of septic shock approximately three months after diagnosis.CONCLUSION The absence of enhancement in the lesion did not rule out PCNSTL.A biopsy approach is advisable for pathological confirmation.
文摘In this editorial I comment on the article,published in the current issue of the World Journal of Clinical Oncology.Primary central nervous system lymphoma(PCNSL)is a disease of elderly and immunocompromised patients.The authors reported clinical results of 19 patients with PCNSL treated with zanubrutinib/high dose methotrexate(HD-MTX)until disease progression.They demonstrated that the combination of zanubrutinib with HD-MTX led to a marked clinical response and tolerability among these patients.They also observed that cerebrospinal fluid liquid biopsy to detect circulating tumor DNA may be a good option for evaluating treatment response and tumor burden in patients with PCNSL.PCNSL is a challenging disease for treatment as these patients present with different neurological states and comorbidities.Treatment has evolved over the years from whole brain radiotherapy to HD-MTX followed by autologous stem cell transplant.Gradually,treatment of patients with PCNSL is going to become individualized.
文摘Hodgkin's lymphoma(HL)is a common,malignant hematological tumor of the lymph nodes and lymphatic system,accounting for 10%of all lymphomas.HL comprises 2 main subtypes:classical HL(cHL)and nodular lymphocyte predominant HL.
文摘BACKGROUND Marginal zone lymphoma(MZL)is an indolent subtype of non-Hodgkin lymphoma(NHL),which is rare clinically with severe rashes as the initial symptom.CASE SUMMARY This study reports a case of MZL with generalized skin rashes accompanied by pruritus and purulent discharge.First-line treatment with rituximab combined with zanubrutinib had poor effects.However,after switching to obinutuzumab combined with zanubrutinib,the case was alleviated,and the rashes disappeared.CONCLUSION For patients with advanced stage MZL not benefiting from type I anti-CD20 monoclonal antibody(mAb)combination therapy,switching to a type II anti-CD20 mAb combination regimen may be considered.This approach may provide a new perspective in the treatment of MZL.

文摘BACKGROUND Primary pancreatic lymphoma(PPL)is an exceedingly rare tumor with limited mention in scientific literature.The clinical manifestations of PPL are often nonspecific,making it challenging to distinguish this disease from other panc-reatic-related diseases.Chemotherapy remains the primary treatment for these individuals.CASE SUMMARY In this case study,we present the clinical details of a 62-year-old woman who initially presented with vomiting,abdominal pain,and dorsal pain.On further evaluation through positron emission tomography-computed tomography,the patient was considered to have a pancreatic head mass.However,subsequent endoscopic ultrasonography-guided fine needle aspiration(EUS-FNA)revealed that the patient had pancreatic peripheral T-cell lymphoma,not otherwise specified(PTCL-NOS).There was a substantial decrease in the size of the pancreatic mass after the patient underwent a cycle of chemotherapy comprised of brentuximab vedotin,decitabine,and oxaliplatin(brentuximab vedotin and Gemox).The patient had significant improvement in radiological findings at the end of the first cycle.CONCLUSION Primary pancreatic PTCL-NOS is a malignant and heterogeneous lymphoma,in which the clinical manifestations are often nonspecific.It is difficult to diagnose,and the prognosis is poor.Imaging can only be used for auxiliary diagnosis of other diseases.With the help of immunostaining,EUS-FNA could be used to aid in the diagnosis of PPL.After a clear diagnosis,chemotherapy is still the first-line treatment for such patients,and surgical resection is not recommended.A large number of recent studies have shown that the CD30 antibody drug has potential as a therapy for several types of lymphoma.However,identifying new CD30-targeted therapies for different types of lymphoma is urgently needed.In the future,further research on antitumor therapy should be carried out to improve the survival prognosis of such patients.
文摘To the Editor:Mantle cell lymphoma(MCL)is a rare subgroup of B-cell nonHodgkin’s lymphoma(NHL)that occurs in approximately 6%of NHL patients.Chronic hepatitis and cirrhosis may promote hepatocellular carcinoma(HCC)development.Here,we report an even rarer case with coexisting HCC and MCL.
文摘BACKGROUND Helicobacter pylori(H.pylori)eradication treatment for primary gastric mucosaassociated lymphoid tissue(MALT)lymphoma has already been established.However,t(11;18)(q21;q21)/API2-MALT1 translocation-positive lesions are a type of primary gastric MALT lymphoma in which a response to eradication treatment is difficult to achieve.In addition,trisomy 18 may be associated with diffuse large B-cell lymphoma(DLBCL)transformation of gastric MALT lymphoma.CASE SUMMARY A 66-year-old man was diagnosed with MALT lymphoma in the ascending colon by colonoscopy and biopsy.Two years later,esophagogastroduodenoscopy revealed chronic atrophic gastritis that was positive for H.pylori,and eradication treatment was administered.Two years and nine months later(at the age of 70),a new ulcerative lesion suggestive of MALT lymphoma appeared in the gastric body,and six months later,a similar lesion was also found in the fundus.One year later(4 years and 3 months after H.pylori eradication),at the age of 72,the lesion in the gastric body had become deeper and had propagated.A biopsy revealed a pathological diagnosis of DLBCL.Both MALT lymphoma lesions in the ascending colon and DLBCL lesions in the stomach were positive for the t(11;18)(q21;q21)/API2-MALT1 translocation,and trisomy 18q21 was also detected.After 6 courses of R-CHOP(rituximab,cyclophosphamide,doxorubicin,vincristine and prednisone)chemotherapy,all of the above lesions disappeared[complete remission(CR)],and CR has been maintained for more than 3 years.In addition,both the colonic and gastric lesions were proven to have the same clonality.CONCLUSION Because the patient had a MALT1 translocation with trisomy 18q21,it was thought that this gastric MALT lymphoma developed independently of H.pylori infection and progressed.
文摘Dear Editor,We present a rare case of a primary penile follicular center non-Hodgkin lymphoma and a review of the available literature on this condition.A BCL2 gene transposition which was identified with fluorescent in situ hybridization(FISH)molecular analysis is a unique manifestation not previously reported to the best of our knowledge.A 67-year-old man presented with a 3-month history of a small nodule on the left side of the corona of glans penis.The patient had no significant medical or family history.The patient underwent excision and biopsy of the penile lesion with a 0.5 cm macroscopic margin under local anesthesia and sedation.He was discharged on the day of surgery,and there were no postoperative complications or adverse events.The informed consent was obtained from thepatient.
文摘BACKGROUND Chemotherapy for malignant tumors can cause brain changes and cognitive impairment,leading to chemotherapy-induced cognitive impairment(CICI).Current research on CICI has focused on breast cancer and Hodgkin’s lymphoma.Whether patients with non-Hodgkin’s lymphoma(NHL)undergoing chemo-therapy have cognitive impairment has not been fully investigated.therapy have cognitive impairment has not been fully investigated.AIM To investigate whether NHL patients undergoing chemotherapy had cognitive impairments.METHODS The study included 100 NHL patients who were required to complete a compre-hensive psychological scale including the Brief Psychiatric Examination Scale(MMSE)at two time points:before chemotherapy and within 2 wk of two chemo-therapy courses.A language proficiency test(VFT),Symbol Number Pattern Test(SDMT),Clock Drawing Test(CDT),Abbreviated Daily Cognition Scale(ECog-12),Prospective and Retrospective Memory Questionnaire,and Karnofsky Perfor-mance Status were used to assess cognitive changes before and after chemo-therapy.RESULTS The VFT scores for before treatment(BT)and after treatment(AT)groups were 45.20±15.62,and 42.30±17.53,respectively(t-2.16,P<0.05).The CDT scores were 8(3.5-9.25)for BT and 7(2.5-9)for AT groups(Z-2.1,P<0.05).Retrospective memory scores were 13.5(9-17)for BT and 15(13-18)for AT(Z-3.7,P<0.01).The prospective memory scores were 12.63±3.61 for BT and 14.43±4.32 for AT groups(t-4.97,P<0.01).The ECog-12 scores were 1.71(1.25-2.08)for BT and 1.79(1.42-2.08)for AT groups(Z-2.84,P<0.01).The SDMT and MMSE values did not show a significant difference between BT and AT groups.CONCLUSION Compared to the AT group,the BT group showed impaired language,memory,and subjective cognition,but objec-tive cognition and execution were not significantly affected.
文摘BACKGROUND Anaplastic lymphoma kinase(ALK)-positive large B-cell lymphoma(LBCL)is an aggressive and rare variant of diffuse LBCL.Herein,we report an uncommon case of stage IE extranodal ALK-positive LBCL initially originating in the bulbar con-junctiva.CASE SUMMARY A 63-year-old woman presented with a mass in the left bulbar conjunctiva that had persisted for six months,accompanied by swelling and pain that had per-sisted for 3 d.Eye examination revealed an 8 mm slightly elevated pink mass in the lower conjunctival sac of the left eye.Microscopically,the tumor was com-posed of large immunoblastic and plasmablastic large lymphoid cells with scattered anaplastic or multinucleated large cells.Immunophenotypically,the neoplastic cells were positive for ALK,CD10,CD138,Kappa,MUM1,BOB.1,OCT-2,CD4,CD45,EMA,CD79a,CD38,and AE1/AE3,and negative for CD20,PAX5,Lambda,BCL6,CD30 and all other T-cell antigens.The results of gene rearrangement tests showed monoclonal IGH/IGK/IGL and TCRD rearran-gements.Fluorescence in situ hybridization studies did not reveal any BCL2,BCL6 or MYC rearrangements.Furthermore,Epstein-Barr virus was not detected by in situ hybridization in the lesions.Based on the histopathological and imaging examinations,the neoplasm was classified as stage IE ALK-positive LBCL.No further treatments were administered.At the 6,15,and 21 mo postoperative follow-up visits,the patient was in good condition,without obvious discomfort.This case represents the first example of primary extranodal ALK-positive LBCL presenting as a bulbar conjunctival mass,which is extremely rare and shares morphological and immunohistochemical features with a variety of other neo-plasms that can result in misdiagnosis.CONCLUSION Awareness of the condition presented in this case report is necessary for early and accurate diagnosis and appropriate treatment.
文摘BACKGROUND Angioimmunoblastic T-cell lymphoma(AITL)is a common subtype of peripheral T-cell lymphoma.Approximately half of patients with AITL may concurrently present with hypergammaglobulinemia.Increased numbers of plasma cells in the bone marrow are commonly observed at diagnosis.These tumors mimic plasma cell myelomas,hindering a conundrum of clinical diagnoses and potentially delaying appropriate treatment.CASE SUMMARY A 78-year-old woman experienced poor appetite,weight loss of 5 kg,fatigue 2 months before presentation,and shortness of breath 2 d before presentation,but no fever or night sweats.Physical examination revealed splenomegaly and many palpable masses over the bilateral axillary regions,approximately>2 cm in size,with rubbery consistency and no tenderness.Blood tests revealed anemia and thrombocytopenia,lactate dehydrogenase level of 153 U/L,total protein level of 10.9 g/dL,albumin to globulin ratio of 0.2,and immunoglobulin G level more than the upper limit of 3000 mg/dL.The free kappa and lambda light chain concentrations were 451 and 614 mg/L,respectively.A pathological examination confirmed the diagnosis of AITL.The initial treatment was the cyclophosphamide,epirubicin,vincristine,and prednisolone regimen.Following this treatment,pleural effusion was controlled,and the patient was discharged in a stable condition and followed up in our outpatient department.CONCLUSION This report highlights the importance of differentiating reactive plasmacytosis from plasma cell myeloma in patients with hypergammaglobulinemia.A precise diagnosis of AITL requires a comprehensive evaluation,involving clinical,immunophenotypic,and histological findings conducted by a multidisciplinary team to ensure appropriate treatment.
文摘BACKGROUND The gastrointestinal tract is a well-known extranodal site of lymphoma.B-cell lymph-oma is the most common type,while T-cell lymphoma is uncommon.Primary gastrointestinal lymphoma mainly occurs in the stomach and small intestine,and the colon is less frequently involved,especially in females.CASE SUMMARY A 45-year-old woman was admitted to our hospital for physical examination.Gastroenteroscopy revealed a visible pedunculated polyp in the transverse colon,for which endoscopic submucosal dissection(ESD)was performed.Pathology suggested highly active proliferation of T lymphocytes with atypical hyperplasia.CONCLUSION A middle-aged female patient was found to have colonic T-cell lymphoma by endoscopy.The lesion was successfully removed by ESD,and the surgical margin was negative.It is essential to raise awareness of colonic T-cell lymphoma and choose the appropriate treatment.
